Cler

Over half of Swedish homes fail basic air quality standards. That’s not a footnote, it’s the problem.

Today’s ventilation systems run on filters that need constant replacing, cost time and money, and can’t even be recycled once they’re done.

CLER built something different: an air purification concept that needs no filter changes at all. For property owners, that means up to 50% less energy use and emissions, and a sharp drop in waste.

Founded by Haoge Li, Johan Nordenadler, Marcus Grünerwald and Tommy Myrvang, CLER is rethinking indoor air from the ground up, not patching the old system, replacing it.
